2-Digit & 3-Digit Addition with Regrouping | Grade 2 Ready

This Grade 2 math worksheet provides comprehensive practice for students mastering addition with regrouping. By solving 18 themed problems, learners build fluency in place value strategies for both 2-digit and 3-digit numbers. The space-themed mission keeps students engaged while they develop the computational accuracy required for higher-level arithmetic and multi-step problem solving.

At a Glance

• Standard: CCSS.MATH.CONTENT.2.NBT.B.7 — Add within 1000 using place value strategies and regrouping
• Skill Focus: Multi-digit addition with regrouping
• Format: 5 pages · 18 problems · Answer key included · PDF
• Best For: Independent practice or homework
• Time: 20–30 minutes

The PDF contains 5 pages of vertical addition problems designed for clarity and ease of use. Part 1, titled Space Cadet, focuses on 16 problems involving 2-digit addition with regrouping. Part 2, titled Astronaut, introduces 3-digit addition to challenge students and extend their learning. The layout is clean with large boxes for student work, and a full answer key is provided for quick grading or student self-correction.

Zero-Prep Workflow

• Print: Select the 5-page PDF and print enough copies for your class in approximately 30 seconds.
• Distribute: Hand out the Space Addition mission to students as a morning warm-up, math center activity, or homework assignment.
• Review: Use the included answer key to check for common regrouping errors in the tens or hundreds place. Total teacher prep time is under 3 minutes.

This resource aligns with CCSS.MATH.CONTENT.2.NBT.B.7, which requires students to add and subtract within 1000 using concrete models or strategies based on place value. It specifically targets the written method of regrouping, ensuring students understand how to carry values to the next column. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

Use this as a formative assessment after teaching the carrying method. Observe if students are correctly placing the regrouped digit in the next column. It also serves as an excellent sub-plan because the space theme and clear instructions allow students to work with minimal teacher intervention for 25 minutes. The progression from 2-digit to 3-digit tasks allows for natural differentiation within the same packet.

Designed for Grade 2 students, it also supports Grade 1 advanced learners or Grade 3 students needing remediation. It pairs perfectly with base-ten block manipulatives or a place-value anchor chart to help students visualize why regrouping occurs when a column exceeds nine. The vertical format reinforces the alignment of ones, tens, and hundreds places.

According to the RAND AIRS 2024 report, structured practice in multi-digit addition is essential for developing the procedural fluency required for multi-step problem solving. This worksheet targets CCSS.MATH.CONTENT.2.NBT.B.7 by providing 18 focused opportunities for students to apply regrouping strategies. Research from Fisher & Frey (2014) emphasizes that themed, scaffolded practice—such as the transition from Space Cadet 2-digit tasks to Astronaut 3-digit tasks—supports the gradual release of responsibility. By isolating the regrouping skill within a familiar vertical format, this resource ensures students master the mechanics of place value before moving to complex word problems. The inclusion of a clear answer key facilitates immediate feedback, a critical component of effective math instruction identified by NAEP. This 5-page PDF is a reliable tool for classroom teachers seeking to bridge the gap between conceptual understanding and computational mastery.
